摘　要
在阅读过程中附带地习得词汇是学习者扩大词汇量的一个重要方式，这也是二语习得领域一个广泛研究的课题。然而，关于附带词汇习得还有许多未解决的难题。一些学者指出，词汇的附带习得是一个复杂的过程，它的发生受到很多因素的制约，如学习任务、语境线索、学习者的词汇量、猜词能力以及认知风格等。尽管有许多关于这些因素的研究，但认知风格对附带词汇习得的影响却没有引起人们的关注。
本文从场认知和歧义容忍度两个纬度对学习者的认知方式进行分析,探讨了英语学习者的认知方式与词汇附带习得的相关关系，同时还探讨了高效词汇习得者和低效词汇习得者在认知方式上的差异。全文共有五部分组成：第一部分介绍了本项研究的目的和意义；第二部分介绍了认知风格和词汇附带习得的研究现状及理论基础；第三部分详细介绍了本项研究中受试，测试工具和研究步骤等情况；第四部分报告了数据统计分析的结果及相关的讨论；最后一部分得出结论，并提出本研究对理论研究与教学的启示意义，同时指出本研究的不足及对今后研究的建议。
来自河南科技大学120名非英语专业学生参加了这次调查，受试接受了关于认知风格的问卷调查和两次阅读后的词汇测试。通过对收集的数据进行分析，结果发现，场独立和高歧义容忍度与受试习得词汇的数量具有显著的相关性，高效词汇习得者与低效词汇习得者在场独立和歧义容忍认知方式上存在显著差异。
本研究的结果对中国的英语词汇教学具有一定的理论和实践意义。首先，它肯定了认知方式在附带词汇习得中的作用，说明语言学习者在认知方式上的个体差异对语言学习过程有一定的影响。其次，它有利于中国英语教师鼓励学生进行大量的课外阅读以扩大词汇量。
关 键 词：认知方式，场独立，歧义容忍度，附带词汇习得
论文类型：应用研究

ABSTRACT
Learning words incidentally through extensive reading is an important way for language learners to expand their vocabulary. It is also an extensively research topic in the field of second language acquisition. However, there are still many unsettled questions about incidental vocabulary acquisition. Some scholars point out that incidental vocabulary acquisition is very complex and there are many factors that may affect the outcome. These factors include richness of context clues, learning task, and learners’ vocabulary size, cognitive style, etc. Despite the fact that a series of studies have researched on these factors, the factor of learners’ cognitive style is largely neglected.
The present study probes into cognitive style from two dimensions---field dependence/independence and ambiguity tolerance/intolerance, explores the relationship between subjects’ cognitive style and their performance on incidental vocabulary acquisition through reading. Besides, the differences between effective learners and ineffective learners in their cognitive style have been investigated. There are five parts in this thesis. Part one starts with a brief introduction to the aims and significance of this investigation. In Part two, we present a survey of research and theories of cognitive style and incidental vocabulary acquisition. In Part three, we first advance the hypotheses, then provide some information concerning the subjects, instruments as well as the procedure of the investigation. Part four presents the data analysis and discussion about the results. Part five is devoted to the conclusions drawn from the present study. Furthermore, implications and limitations of the present study and suggestions for further research are discussed.
120 non-English majors in Henan University of Science and Technology are chosen as the subjects and they take the questionnaire for cognitive styles and two vocabulary tests after reading. The data collected were analyzed to find out the possible relationship between cognitive styles and incidental vocabulary acquisition performance. The results indicated that the amount of gained word knowledge significantly correlated with the degree of field independence and ambiguity tolerance, and that there is a significant difference between effective learners and ineffective learners.
The findings have both theoretical and pedagogical implications. First, they have confirmed the effects of cognitive style on language learning process, which shows that individual difference in cognitive style has certain effects on the vocabulary learning. Second, they are beneficial for the Chinese English teachers to encourage students to carry out a large amount of extensive reading in order to improve their vocabulary growth.
KEY WORDS: cognitive style, field independence, ambiguity tolerance, incidental vocabulary acquisition
